At a minimum, gardens provide spatial experiences for our senses.

As we enter and leave our home, we move through our garden and enjoy changing scenery, texture and fragrance. We can be alone in our garden or with others. We can sit, read, relax, and dream, or play vigorously in our garden. We can groom our plants or our pets in our garden. We can stare at a fire, the stars, or a reflection in water; absorb sunrise and admire sunset;
howl at the full moon, do yoga or play cards;
watch spiders spin and raindrops fall.

At their best, gardens are potent, sacred spaces.
